DELAY RETURN GAS SPRING - A delay return gas spring including a piston at least partially received in a cylinder for reciprocation between extended and compressed positions over a cycle including a compression stroke and a return stroke. A seal disposed between the cylinder and the piston separates a primary chamber on one side of the seal from a secondary chamber on another side of the seal during a portion of the cycle. A passage communicates with the secondary chamber and with the primary chamber. The seal is relatively movable between an open position permitting free flow of gas through the passage to a closed position at least partially restricting gas flow through the passage so as to permit gas in the secondary chamber to be compressed in response to movement of the piston toward its extended position, thereby reducing a net return force on the piston and decreasing a velocity of the piston.

Gas Spring - A gas spring for forming equipment, including a piston received at least partially in a cylinder for reciprocation between extended and retracted positions, and including a throttling passage disposed between the piston and the cylinder in fluid communication between first and second pressure chambers during at least a portion of the reciprocation of the piston. The throttling passage is of variable cross-sectional area, which varies with a length of the passage to at least partially restrict gas flow therethrough in a manner varying with return of the piston toward its extended position to decelerate the piston at a predetermined rate.

CONFIGURING THE OPERATION OF AN ALTERNATING PRESSURE VENTILATION MODE - Systems and methods for configuring the operation of an alternating pressure ventilation mode are provided. According to one embodiment a configuration method includes monitoring gas flow between a patient and a ventilation system. Based on the monitoring, a peak expiratory flow rate (PEFR) is determined Information indicative of values of parameters of the ventilation mode are received, including a higher pressure setting, a lower pressure setting and a duration of the higher pressure setting. User input is also received indicative of a target percentage of PEFR at which the ventilation system should cycle from the lower pressure setting to the higher pressure setting. Based on the target percentage, a duration of the lower pressure setting is programmatically determined. Finally, the ventilation system is configured to automatically cycle between the higher and lower pressure setting at a predetermined flow based on the parameters and the duration of the lower pressure setting.

DYNAMIC ADJUSTMENT OF TUBE COMPENSATION FACTOR BASED ON INTERNAL CHANGES IN BREATHING TUBE - This disclosure describes systems and methods for adjusting a determination of the amount of breathing assistance a patient requires while on a ventilator. In general, in determining the amount of breathing assistance required, the ventilator takes into account an airflow resistance attributable to the tube used to deliver ventilation to the patient's lungs. A tube compensation factor is calculated using a tube compensation algorithm, or similar equation. In particular, the tube compensation factor represents the resistance to airflow attributable to the breathing tube itself based on, inter alia, frictional drag, turbulence, and an internal diameter of the tube. Changes in the tube during ventilation impact the calculation of the breathing assistance required by the patient and are accounted for when compensating for the breathing tube.

SYSTEM AND METHOD FOR REDUCING RADIATOR SIZES FOR LOW TEMPERATURE FUEL CELL SYSTEMS - A fuel cell cooling system includes a fuel cell having a liquid loop that produces water vapor. An antifreeze cooling loop includes an inductor that receives the water vapor and introduces the water vapor to an antifreeze. The water is separated from the antifreeze and returned to the liquid cooling loop as liquid water after the mixture of condensed water vapor and antifreeze has passed through a radiator. Water in the liquid cooling loop exits the fuel cell and passes through a restricting valve thereby lowering the pressure of the water. A flash cooler downstream from the restricting valve collects the water vapor and provides it to the inductor in the antifreeze cooling loop. The flash cooling in the first cooling loop provides a first cooling capacity that is low temperature and pressure compatible with fuel cell operation.
